Halide-perovskite nanolasers have demonstrated fascinating performance owing to their efficient light emission and low-threshold lasing at room temperature as well as low-cost fabrication. However, being synthesized chemically, controllable fabrication of such nanolasers remains challenging, and it requires template-assisted growth or complicated nanolithography. Here, we review recent achievements for the fabrication of light-emitting nanoparticles and nanolasers by laser ablation of a thin film on glass with femtosecond laser beams [1-3]. The fabricated nanoparticles and nanolasers are made of MAPbBrxIy perovskite, which is a popular material in optoelectronics and photovoltaics. High-speed fabrication and reproducibility of nanostructures parameters, as well as precise control of their location on a surface, make it possible to fabricate centimeter-sized arrays of the nanolasers. Our finding is important for direct writing or printing of fully integrated coherent light sources for advanced photonic and optoelectronic circuitry [4].
